There is the original Project approved baseline. The project evolves, the project gets behind, so there is a major change in phasing to bring it back a bit. Can you approve a re-phasing project as a Re-baseline if it is negative? Can you have a defacto baseline? Meaning shouldn't we compare the current updates to the "changed phasing" version - or do you have to keep comparing to the Original Legal baseline? What are the general legal issues to keep in mind with re-baselines - it seems like they should occur almost each time projects change sometimes.
